BAG.

SPECIFICATION forming part of Letters Patent No. 326,665, dated September 22, 1885.

Application filed October 6, 1884.

To all whom it may concern.-

Be it known that 1, JOHN MADDooK, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, haveinvented certain new and useful Improvements in Bags; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit ap- IO pertains to make and use the same.

My invention relates to improvements in the sewed bags which are used for holding flour. These bags are made from burlap or other material that is loose in texture, and they are I 5 usually made with a seam across the bottom and up one side. As heretofore constructed these bags have been objectionable,for the reason that under the pressure of the flourin the bag the stitches of the seam would push forward, displacing the fiber of the cloth, and leave a small opening along each side of the seam, through which the flour would sift, thereby causing a great deal of waste.

The object of my invention is to provide a sewed bag that shall be free from this objection, while it is at the same time no more expensive than the ordinary sewed bag.

My invention consists in the bag hereinafter described, and particularly pointed out in the claim.

Figure 1 in the accompanyingdrawings isa section of a bag made in accordance with my invention. Figs. 2 and 3 are detailsillustrating the manufacture of the same. Figs. 4

and 5 are sections of abag madein the common way. Figs. 6 and 7 are views showing material such as is usedin the manufacture of these bags. The said several figures are on an enlarged scale. Fig. Sis a perspective of a bag made according to my invention, it being rep resented as turned partly inside out to show the folds at the seam.

In the drawings, A, Figs. 6 and 7, represents a piece of burlap, this being the material usually employed in the manufacture of flour-bags. It willbe seen that this is a material thatis loosein texture. If a row of stitches be run across the material, as indicated by oin Fig. 6, and any pressure is applied to this row of stitches in the direction of the arrowin Fig.

(No model.)

6, the threads I) b of the material, that are substantially parallel with the row of stitches and upon the side opposite that to which pressure is applied,will be crowded together,thestitehes c and the cross-threads Z; Z) sliding on the 1011- gitudinal threads a a, and an opening will be left above the stitches, as indicated in Fig. 7. These figures, together with the above explanation, illustrate the objection thatis overcome by my invention. This objection willbe 61) more fully understood by reference to Figs. 4 and 5, each of which is a section across the seam of a flour-bag as constructed prior to my invention. The edges of the material that are united to form the seam are each folded back 6 5 upon itself, as shown in Fig. 4. A row of stitches, c, is then passed through the four thicknesses of the material from one-half to three-quarters of an inch from the edges of the folds, or so far from the edges that the bag is subject to the objection herein specified. This row of stitches extends across the longitudinal threads at a, at substantially right angles there to, and substantially parallel with the crossthreads I) b. This seam is upon the inside of the bag when ready for use, and when the bag is filled with flour the weight upon each side of the seam presses upon the material, and as the loose cross-threads between the stitches and the edges of the folds do not offer so sufficient resistance to prevent it, the stitches press along thelongitudinal threads, crowding the loose cross-threads aforesaid closely to gether, and leaving, consequently, an opening behind each stitch. There is thereforeaspace 8 along each side of the seam, as shown in Fig. 5, at which there are no cross-threads, they having been displaced,and through these open ings the flour continually Works out.

Figs. 1, 2, and 3 are views which illustrate 0 a bag made in accordance with my invention. The material of which the bag D is made is folded back at the edges for about an inch or an inch and a half. This folding of the material causes bends or turns in the longitudinal 5 threads a a, as shown in Figs. 1 and 2. The folded edges are brought together, as shown in Fig. 2, and the row of stitchesc is run through the four thicknesses of the material close to the edges of the folds across the longitudinal IOO threads at a, and in the direction of the crossthreads I) b. The cross-threads?)b,that-are between the row of stitches and the edges of the folds, are held closely between these stitches and the turns or bends in the longitudinal threads a; a. The cross-threads .are unable to move when the pressure of the stitches comes against them, because the turn or bend in the 1 longitudinal threads prevents any movement on their part, and as they cannot move out of place the stitches are prevented from moving forward out of place, and the opening beside the stitches is thus precluded. Theseam will therefore remain tight and fi rm under press- I ure, and the bag can be used as safelyasiabag constructed without a seam.

The terms longitudinal threads and cross-threads are used for convenience merely, longitudinal being applied to the threads of the material across which the row of stitches extends, and cross-threads to those which extend substantially in the same direction as the row of stitches. Threads .being placed close to the turns, substantially as described, to lock the cross threads orfibers between the stitches and the turns in the longitudinal threads or fibers, and preclude movement 'of such cross-threads and the stitches, all substantiallyas described, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
